BUTTONHOLE-STRiP AND METHOD OF MAKING SAME.

SPECIFICATION forming part of Letters Patent No. 514,415, dated February6, 1894.

Application filed April 22, 1893. Serial No. 471,410. (No model.)

To 6025 whom it may concern.-

Be it known that I, FREDERICK A. 000K, of the city of St. Louis, in theState of Missouri, have invented certain new and useful Improvements inButtonhole-Strips and Methods of Making the Same, of which the followingis a specification.

My invention reiates to the manufactu re of button-hole stripsforinsertion into garments of various natures, and consists first in anovel method hereinafter described and claimed for manufacturing suchstrips and secondly in an improved button hole strip having thecharacteristics hereinafter pointed out and claimed.

In order that my invention may be fully understood, I will describe itin detail with reference to the accompanying drawings, which form a partof this specification and in which-- Figure I is a face View of one ofthe flat strips of fabric with the button-holeslits cut in the inneredges thereof. Fig. II is a similar View, illustrating the plain seamsaround each slit, by which a pair of such strips are joined around thebutton-hole. Fig. III is an edge view of the united strips beforeturning. Fig. IV is a transverse section of the same on the line IV-IV,Fig. II. Fig. V is a face view of the same after turning. Fig. VI is anedge view of the same. Fig. VII is a transverse section thereof on theline VII- VII, Fig. V. Fig. VIII is a face View of the finishedbutton-hole strip. Fig. IX isa view of a portion of a coat with one ofmy improved button-hole strips applied.

1 represents a garmentto which I have shown my improved button-holestrip applied. The garment I have illustrated is a coat, but it will beunderstood that the invention is not confined to use in connection withany particular or prescribed garment, it being evident that it is asreadily adaptable to various descriptions of garments other than the onedesignated.

In forming the stripI first cut from the material, of which the strip isto be formed, two curved pieces 2, as illustrated in Figs. I and II. Inthese pieces I form slits 3 extending from the curved edge of the pieces2, of suitable length and distance asunder for the desired buttonholes.The two pieces are then laid together so that the slits 3 correspond,and one or more rows 4 of stitches are formed around the edges of thesaid slits, thus firmly joining the two pieces of the strip together andforming hems, as illustrated in Figs. II and IV. As the next step, Iturn the strip inside out, so that what was previously the inside of thestrip is now the outside and the edges of the slit 3 that projectedbeyond the rows 4 of stitches, are turned within, and at the same timethe strip 3 is straightened, as illustrated in Fig. V. Figs. V, VI andVII represent the strip at this stage of its construction. As showninFig. V, the inner ends of the slits 3 come together, and the outer endsassume an expanded and rounded form, and by reason of the turning of thefabric, the wall of the button-hole is formed by a folded edge, insteadof, as is usual, acut edge. When the strip has been turned as described,the sides of the slit 3, by the stiffness of the materialsometimes used,bulges outward, as illustrated in the section, Fig. VII, and for thepurpose of securing two Webs of the strip in the required fiat conditionat the sides of the slits and also for the purpose of strengthening thebutton-holes and keeping them in shape, 1 form one or more rows 5, ofstitches around the slit, and one or more rows 6 of stitches across theinner ends of the slits, thus finishing the now completed button-hole 7.

For the purpose of joining the edges of the pieces 2, one or more rows8, of stitches are formed around the outer edge of said pieces and afterpressing the button-hole strip in the completed condition shown in Fig.VIII, is ready for insertion into a garment, and may be inserted asshown in Fig. IX, where it appears between the inner and outer facing ofthe garment and is secured by one or more rows 9 of stitches.

It will be observed that the entire blank of which my button-hole stripis formed when out on a series of angles as illustrated in Fig. I,assumes an approximately curved form, and hence I speak of it as acurved strip. The same efiect may be produced though in a less perfectway by cutting the blanks in the form of a circular are, or otherregular curve.

Having thus described my invention, the following is what I claim. asnew therein and desire to secure by Letters Patent:

1. A blank for a button hole strip, consisting of two fiat curved pieceshaving straight edges forming angles, and slits extending inward fromthe projecting angles, substantially as described.

2. The method of making button-hole strips which consists in cutting thematerial in concave-convex blanks of the form required, slitting thesame transversely from the convex edge, uniting two such blanks byseamsaround the slits, reversing the united strips to present a folded edgearound the button-holes stitching by which the margins are secured; 2 5

substantially as described.
